Concept:
The nucleus of the Cell
- The cell is the basic building block of all living beings.
- The nucleus is the special structure located generally at the center of the cell.
- The nuclear membrane separates the cytoplasm from the nucleus.
- The nucleus contains a central part called nucleolus and chromosomes.
- Chromosomes and nucleolus coexist in the nucleus. Chromosomes are not present in the nucleolus.
Chromosomes and Genes
- Chromosomes carry genes and help in the inheritance or transfer of characters from the parents to their children.
- The chromosomes can be seen only when the cell divides.
- The credit for the discovery of chromosomes goes to Strasburger as he first described the chromosome structure seen in the nucleus during cell division.
- Usually, chromosomes are rod-shaped, elongated, or dot-like in shape with sizes varying from 0.5 to 32 micrometer.
- In humans, 23pairs of chromosomes are found i.e. 46 in numbers.
Conclusion:
- Chromosomes are present in the nucleus of the cell. So, all the given options are wrong.
- The correct option is None of these.
Additional Information
- The cell membrane is also known as the plasma membrane.
- It is a porous structure that allows the exit and entry of certain materials according to its requirement.
- This is the major function of the cell membrane.
- The cytoplasm is between the cell and the nucleus.
- Cell organelles like mitochondria, Golgi bodies, ribosomes, etc. are present in the cytoplasm.
- Mitochondria is called the powerhouse of cells and is responsible for cellular respiration.
- vacuole is open space between cell which is used for storing food.
- Plastids are double-membrane organelles found in the plant cell. They contain pigments that help the plant in photosynthesis.
